Commercial & Architectural Thermal Break Fixed Picture Windows
Grandor Door Industry Co., Ltd. designs, extrudes, and manufactures factory-direct thermal break aluminum fixed windows engineered specifically for global importers, real estate developers, facade contractors, and architectural distributors. Because fixed picture windows contain no operable mechanical sashes or hinges, they deliver superior structural strength, complete air-tightness, and zero water penetration under extreme storm conditions.
Manufactured inside our integrated 155,000 m² facility in Foshan, Guangdong, every fixed window profile is constructed using high-precision 6063-T5 architectural aluminum alloy combined with structural polyamide thermal isolation strips. This enables modern buildings to feature expansive glass spans while easily meeting strict energy efficiency ratings (Low U-Values and SHGC requirements).
Why Global Procurement Buyers Specify Grandor Fixed Windows
Fixed windows offer the highest cost-to-performance ratio in building envelope design. By eliminating complex operating hardware, Grandor Door Industry Co., Ltd. delivers oversized structural glass walls with slim frame sightlines, zero seal degradation over time, and industry-leading acoustic barrier ratings.

Key Structural Advantages of Grandor Fixed Picture Windows
1. Unobstructed Panoramic Sightlines
Ultra-slim aluminum frames maximize clear glass area, allowing interior spaces to be filled with natural daylight while preserving panoramic outdoor views.
2. Superior Energy Efficiency
Elimination of operable sash gaps coupled with multi-chamber PA66 thermal strips prevents thermal bridging, significantly reducing building HVAC operating costs.
3. Extreme Storm & Wind Load Resistance
Corner-crimped extruded aluminum profiles combined with thick structural double-glazing handle extreme negative wind pressures in high-rise coastal developments.
4. Custom Geometric Configurations
In-house aluminum extrusion and bending technology allow production of custom rectangular, arched, triangular, trapezoidal, and floor-to-ceiling glass wall shapes.
Complete In-House Manufacturing & Quality Control (E-E-A-T)
With over 16 years of direct manufacturing experience, Grandor Door Industry Co., Ltd. eliminates quality discrepancies by conducting every critical production stage within our own facility. From raw aluminum ingot extrusion to vertical automated powder coating lines, CNC precision profile cutting, automated glass tempering, and insulated glass unit (IGU) sealing, our multi-stage quality checks ensure every unit shipped matches shop drawing tolerances.
Prior to export packaging, fixed window frames undergo strict dimensional alignment, glass seal compression verification, and pre-shipment structural testing. We regularly accommodate nominated third-party inspectors to review consignment quality before container dispatch.
Global Project Packaging & Freight Support
Exporting to more than 60 countries requires robust protective packaging. Grandor fixed windows are packed with multi-layer protective film, impact-resistant foam corner caps, and fully enclosed wooden crates to ensure zero glass breakage or surface scratching during maritime container transit.
